SPINNING-FRAME.

Specification of Letters Patent.

Application filed November 22, 1911.

To all 'whom it may concam.'

Be it known that I, HERBERT W. OWEN, a citizen of the United States, anda resident of Dover, in the county of Straiford and State of NewHampshire, have invented certain new and useful Improvements inSpinning-Frames, of which the following is a specification.

This invention relates to spinning ma chines, and has particularreference to mechanism connected with the ring rail to effect thechanges in its vertical position.

When dofting, the ring rail is usually moved to a position below itslowest eXtreme when traversing, to facilitate access to the bobbin. Thenthe machine is run slowly, as by working the shipper lever back andforth, so as to give slack yarn to enable the' full bobbins to beremoved, and to furnish the slack yarn to be fastened ready for theoperation on the new bobbins. Then when the g new bobbins are all inplace and the machine any stoppage, it is customary to go through thesame operation which is aptly called jiggling. Without considerablepractice, this jiggling is liable to be excessive, and furthermore itrequires considerable physical edort.

The object of my present invention is to provide means whereby thisjigglin'g, or series of short traverses, may be imparted to the ringrail whenever desired, by power, thus avoiding the expenditure ofphysical effort by the dolfer, and causing such short traverses to beuniform and with a predetermined degree or amountnof motion.

To these ends, the invention consists in the construction andcombination of parts, substantially as hereinafter. described andclaimed.

Of the accompanying drawings,-Figure 1 is a front elevation of so muchof a spinning machine as is necessary to illustrate my invention in oneof its embodiments. Fig. 2 is a detail end view, looking from the leftof Fig. 1.

"the usual gear of the machine.

Similar referenceI characters indicate the same or similar parts in boththe views.

The spindle rail 15 supports the spindles in the usualmanner, and thering rail 17 carries rings for travelers, said ring rail being supportedupon lifter rods. To avoid unnecessary drawings, only one spindle isshown, as at 16, one ring 18, one traveler 19, and one lifter rod 20.The complete machine has a plurality of lifter rods each actuated in anupward direction by a rocker 21 under the influence of weight 22. The'rocker 21 has an arm 23 from which a link 24 extends to another rockerarm for another lifter rod. The rocker arm is provided with the usualsegment 25. This segment 25, in a well known type of spinning frame, isconnected by a chain with the builder motion. In the present drawings,such builder motion and the chain therefrom to the rocker arm areomitted to avoid confusion. As shown in the accompanying drawings,however, there is a chain 26 connected at one end to the segment 25 fromwhich it passes under' a sheave 27 carried by a bracket 28 thatissupported by the end frame of the machine. From said sheave 27 the chainpasses upwardly and over a sheave 29 carried by one end of a lever 30which is pivoted at 31 on a pin or stud shaft projecting from the frameof the machine, the other end of said lever 30 carrying a roll 32. Fromthe sheave 29 the chain 26 passes downwardly and is secured to a rotarystud 33 as by being passed through a transverse aperture in said studand the end of the chain having a cotter ring 3&1(` The stud .33 isrotatively mounted in the end frame of the machine and has a hand wheel35 in a position readily accessible to the doffer. In Figf2 the frontroll shaft 36 is illustrated as constructed Vand in the usual positiontherefor, saidA shaft having a gear 37 that is driven by Connected torotate with said shaft as by being secured to the spokes of the wheel 37is a cam 38. This cam is illustrated as circular in form buteccentric-to the axis of the shaft 36 with which it rotates.

It is to be understood of course that the shaft 36, and of course thecam 38 also will be constantly rotating at a uniform speed whenever themachine is spinning. The lever 30 is held normally in substantially theed' at one end to said lever 30 and at the other end to a suitablestationary point. This, or any mechanical equivalent therefor is for thepurpose of normally keeping the roll 32 suiliciently spaced from the cam3S to prevent the lever 30 from being actuated by said cam. Vhenever thedotfer or other operator desires that the ring rail shall be jiggled orhave imparted thereto -a series of short traverses, he simply rotatesthe hand wheel 35 in the direction of the arrow in Fig. 2 so as to windup the chain upon the rotary stud 83 until by doing so the resultingpull upon the chain will cause the roll 32 to bear against the cam 38.The hand wheel is simply held with suiiicient firmness so that theoscillations of the lever 80 under the influence of the rotating camwill not unwind the chain from t-he rotary stud, but will cause thesheave 29 to exert a pull in the bight or loop of chain passing over it,such pull being then transmitted to the portion of the chain whichpasses around the .sheave 27 to the rocker arm 23. Owing to the sheave29 being in a bight of the chain, the amount of motion imparted to therocker arm will be double the amount of motion that is imparted to thesheave 27 by the cam 38 acting upon the roll 32 at the other end of thelever 30, consequently the amount of eccentricity of the cam 38 need bebut very slight.

As long as the hand wheel 35 is held in the manner described, the ringrail will have imparted thereto a series of short traverses, with thesame results that have heretofore been'obtained by the doifer pressinghis foot upon the foot piece 40 carried by the rocker 21. This footpiece 40 is shown in Fig. 1 of the drawings for the purposes ofillustration in connection with the above description, but it will beunderstood of course, that with my improvement, such foot piece 40 willnot be necessary for use to impart the Y short traverses. However, it isdesirable to lever 30 constitutes a movable member which is-normallyseparated from said cam or actuator but is adapted to be manuallyshifted to position where its roll 32 willengage said cam or actuator soas to result in motion being transmitted through the chain to the ringrail.

I claim:-

l. A spinning machine having means for mechanically traversing the ringrail, said means including a power-operated actuator,`

a movable member normally separated from said actuator and adapted to-be manually shifted to position to be operated vby said actuator, andconnections between said movable member and the ring rail to transmitmotion to the latter, said actuator and connections being structurallyindependent of the. builder motion of the machine.

2. A spinning machine having a cam, a lever normally out of position tobe operated by the cam, manually operable means for shifting' the leverto position to be actuated by the cam, and connections between the leverand ring rail for causing the latter to be traversed by said lever. i

3. A spinning machine having a cam, a lever having a roll at one endadapted to contact with said cam, a sheave at the other end of thelever, a chain passing over said sheave and connected at one end to therocker arm of the ring rail lifter mechanism, and means for taking upthe other end of said chain. A

In testimony whereof I have atliXed my signature, in presence of twowitnesses.
